Description

The PT6703 is a fully integrated

13 A switching regulator housed in

a space-saving solderable package. The

PT6703 will operate from either a

3.3V or 5V input to provide a high-

performance low-voltage output that is

programmable over the range 1.1V to

1.85V. This output voltage range is

specifically suited to high performance

碌P and DSP applications that require

core supply voltages below 1.3V. The

voltage control inputs are also TTL

compatible. Additional features in-

clude output short circuit protection,

a 鈥淧ower Good鈥?output, and an over-

voltage protection (OVP) drive.
